isdndebug -- display and control isdn4bsd kernel variables and statistics
isdndebug [-c] [-e] [-g] [-l layer] [-m] [-q] [-r] [-s value] [-u unit]
[-z] [-C] [-Q]
The isdndebug utility is part of the isdn4bsd package and is used to control
the level of debugging output of the isdn4bsd kernel part. Every
layer of the isdn4bsd kernel uses a debugging mask which can be manipulated
using this utility.
A second usage of isdndebug is to display and reset chipset specific statistics
and/or error counters and to display and reset the D-channel
layer 2 (Q.921 LAPD protocol) statistics and error counters.
The following options are available:
-c Display chipset specific statistics and/or error counters.
-e Set debugging mask for the selected layer(s) to display errors
only.
-g Get the debugging mask for the selected layer(s).
-l Specify the layer for which a command applies. Default is all
layers.
-m Set debugging mask for the selected layer(s) to display all possible
debugging messages (maximum output).
-q Display the Q.921 (D-channel layer 2) frame receive/transmit statistics.
-r Set debugging mask for the selected layer(s) to the compiled in
default (reset).
-s Set debugging mask for the selected layer(s) to value. Value can
be specified in any number base supported by sscanf(3).
-u Set the unit numbers for the -c, -q, -C and -Q flags.
-z Set debugging mask for the selected layer(s) to no output at all
(zero).
-H Reset the chipset specific statistics and/or error counters to
zero.
-Q Reset the Q.921 (D-channel layer 2) frame receive/transmit statistics
to zero.
/dev/i4bctl
The command:
isdndebug -g
displays the current debugging level for all ISDN layers
